Xfinity Mobile Representative randomly cancelled my watch line when trying to order a new watch for a different line.

Hi, about a couple months ago, I reached out to support about ordering a watch for another line on my plan. Well in the process of that, the representative told me to confirm the order for the new watch and then I got a notification that my watch line had been cancelled! What makes it more frustrating is that my watch, (Apple Watch Ultra 2), I pay off monthly, so basically you have to have service along with it to pay it off monthly, which makes everything much more complicated or downright impossible for me to get help with/fix. Ive been contacting customer support for the past month or two and since then Ive always just been told that its been brought to their higher up team and that they will get back to me but then immediately after I keep getting upsold on promos and deals that I don't want over and over again, never getting my problem resolved. I don't know what else to do as I would really like to have my watch line active again but customer support just doesn't want to help me and just sell me on other things instead of helping me fix this problem. It's getting to the point I want to cancel my service and switch to someone else.
